The removal of the matrix proved to be quite a challenge.
The resources of the Smithsonian Institution’s Vertebrate Paleontology Preparation Laboratory were drawn upon to remove the plastic atrix with a pneumatic scribe.
LIMITATION OF DAMAGES: While we do everything we can to process all samples with care, samples can be lost at any stage of the process.
We cannot be liable for lost samples or the consequences thereof beyond the price paid for the analysis.
Radiographs revealed a skull with the cranium and mandible disarticulated within the plastic matrix (Figure 1).
The disarticulation suggested that the cranium and mandible were most likely skeletonized at the time of their immersion into the liquid plastic.
If at all possible retain a portion of each of your samples in the unlikely event of loss in shipment or in the laboratory.
